If you were in downtown Evansville Saturday morning, you may have heard the sound of jingle bells. Festive runners gathered at Old National Bank for the Jingle Bell Run. Tri-Staters participated in the 5K run, 5K walk, and the Santa Chase. Runners tie jingle bells to their shoelaces and wear holiday costumes. The run is presented by the Arthritis Foundation, and raises awareness and funds to help prevent, control, and cure arthritis and its related diseases. Organizers say arthritis affects more than 1.3 million people in the Hoosier state.
